[PATCH 12/14] series: Add a signal to notify when a revision is complete

[Damien Lespiau]

To decouple some high level and rather complex parsing code from the
models, let's add a signal when a SeriesRevision is complete.

One can use that signal to hook some logic there, for instance from the
mail parsing code.
